WINDOW-SHADE CARRIER.

Specication of Letters Patent.

Patented Oct. 20, 1908.

Application filed December 23, 1907. Serial No. 407,647.

I To all whom fit may concern:

Be it known that. I, ALBERT C. VAN ERKA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window Shade Carriers, of which the following is a specication.

This invention relates to window-shade carriers, and more particularly a device whereby the shade may be raised or lowered bodily and set at any desired point on the window-casing, the object being to permit light and air to enter at the top of the window above the shade.

The invention comprises a carrier of improved construction, together with means for operating the same as will be fully described hereinafter.

In the accompanying drawing, Figure 1 is an elevation of the invent-ion, parts being shown in section. Fig. 2 is a section on the line 22 of Fig. 1.

Referring specifically to the drawing, 5 denotes a channeled plate secured to one side of the window-casing and having at one edge an overhanging flange 6 in the edge of which is a rack 7. The opposite side of the window-casing is provided with a corres onding channeled plate 5aM having a rack 71. These guideplates extend verti cally on opposite sides of the window-casing and serve to guide and retain the shaderoller carriers and devices to be hereinafter described, the racks 7 and 7a being engaged by pinions carried by the roller. One of the carriers is a plate 8 which is slidably mounted in the channel 5 and on the face of the plate is pivoted at 9 a plate 10 having a projection 11 which is engageable with the rack 7. The plate also has teeth 12 in its edge which mesh with teeth 13 in the edge of a disk 14 pivoted at 15 on the face of the plate 8. The disk 14 also has a projection 16 engageable with the rack 7 To the upper end of the plate 8 is fastened a laterally extending arm 17 and on the plate 10 is a laterally extending arm 18. To these arms are made fast the respective ends of a cord 19 which passes over pulleys 20 and 20a secured in frames 21 mounted on the windowcasing- The pulley 2O is located above the arm 17 and the pulley 20a is below the arm 18. The projections 11 and 16 are normally held in engagement with the rack 7 by means of a spring 22 secured at 23 to the plate 8 and pressing with its free end on a pin 24 projecting from the plate 10.

In the plate 8 is journaled one end of the spindle 25 of the shade-roller, and outside the latter a pinion 26 is fixed on the spindle. This pinion travels on the rack 7 and has shroud-plates 27 which serve to hold the pinion in proper position and in engagement with the rack. On the shade-roller spindle is also secured a sleeve 28 having ratchet teeth 29 engageable by pawls 30 mounted on the ring-plate 3l at the end of the tubular roller 32 to which the cloth shade will be fastened. A spring (not shown) is provided to operate the roller in a well known manner. At the opposite end of the roller the spindle has a shrouded pinion 33 which travels on the rack 7 a, and on Y the spindle is also mounted a roller 34 which travels on the flange of the plate 5a and holds the pinion in engagement with the rack 7 a. The shaderoller spindle is in two sections connected by a slide-coupling 35 which allows longitudinal adjustment to bring the pinions 26 and 33 into proper engagement with the racks.

When the projections 11 and 16 are in engagement with the rack, the carrier plate 8 is locked in the channel 5. yTo release the plate the arm 18 is pulled downwardly by meansof that end of the cord 19 which is attached thereto, which swings the plate l0 on its pivot and withdraws the projection '11 from the rack 7. At the same time, by reason of the gearing between the plate 10 and the disk 14 the latter' also turns on its pivot whereby the projection 16 is also withdrawn from the rack 7. This releases the carrier j plate 8 and permits it to be moved up and down in the channel 5. Upon releasing the cord 19 the spring 23 turns the plate 10 in the direction to reengage the projections 11 and 16 with the rack, whereby the plate 8 is locked in the channel 5.

I claim 1. A shade-roller fixture comprising opposite guides and racks, a slide mounted in one of the guides, a shade-roller spindle journaled at one end in the slide, pinions on op posite ends dof the spindle which engage the racks, a pair of operatively connected rackcatches on the slide, and means for operating the catches.

2. A Shade-roller fixture comprising oppoi site guides and racks, a slide mounted n one l of the guides, a shade-roller spindle ,jouri naled at one end n the Slide, pinons on opposite ends of the Spindle which engage the racks, L mok-catch Carried by the Slide, and an operating-cord connected at oneendlto the slide for elevating the same, and at the otlier end to che oacoli for* Simnltaeisly re`` leasing the Same and lowering the Slide. 10 In testimony whereof I affix my signatui'e',

in presence of two witnesses.
